The astrolib part of this repo is probably obsolete given the existance of astropy

This package does not need to be installed in the sense if of 'pip install', so if you want to you use it, you can either copy a script that you want and add it to the current directory or clone the repo and add the path to PYTHONPATH

The licensing for the programs I wrote myself is GPL3. For all other programs (mainly converted from IDL) I guess the license is either BSD or they are in public domain.
